After Kelloid Surgery, Laser and Local Injection Combination Therapy Proven Effectiveness

Oct 17, 2024

The plastic surgery research team at Boramae Hospital in Seoul Metropolitan Government (Professor Park Joon-ho and Professor Park Ji-woong) announced the results of a study that proved the effectiveness of the therapy combining laser and topical injection in post-keloid surgery management.

Kelloid is a protruding scar that extends beyond the area of existing skin damage by excessive fibrosis. It is at risk of developing up to 15% of the world's population due to the increase in various surgeries and piercings, and it occurs frequently in young adults. Although the exact mechanism of development of keloids has not been clearly identified, various hypotheses have been raised, such as imbalance of growth factors or changes in extracellular matrix. Despite various attempts at keloid treatment, there is currently no clear solution or treatment.

Moreover, keloid is an incurable disease, and many people complain of itching and pain, and cosmetic problems may be accompanied by mental pain. Therefore, laser-injection combination treatment performed with scar plastic surgery by Professor Junho Park will provide efficient and safe treatment options for patients with keloid scarring and is also expected to become a standard for managing keloid scar prognosis.

The study was conducted in 111 patients who underwent keloid scar plastic surgery between March 2019 and June 2022. The research team conducted a retrospective analysis of patients who received laser-injection combination treatment using the precision assessment scale of scarring (mVSS, POSAS), recurrence rate, and patient satisfaction.



A comparison and analysis of treatment prognosis between the group (53) who received laser and injection combination therapy (58) and the group who received injection combination therapy (58) showed statistically significantly higher scar assessment scores (mVSS, POSAS) and lower recurrence rates at 1 year postoperative.

Professor Park Jun-ho said, `We hope this study will help many people suffer from the keloid scar, and we plan to continue research on keloid therapy based on the results of cell and animal experiments on mechanical signaling of keloid and scarring conducted by plastic surgery at Boramae Hospital for many years from now.' In addition, "We will focus more on treating and managing general scars through the latest laser, various injection treatment know-how, and scar management products."," he said.



This study evaluated the efficacy and stability of the treatment combining the Nd:YAG laser and Triamcinolone injection to treat keloid scars and prevent recurrence after surgery, and was recently published in the leading SCI international journal 'Aesthetic Plastic Surgery'.
